Remember that you don’t only need to know what to say but also when to say it. Part of memorizing lines is memorizing your cues. In some cases, your cue is the last line spoken by a character sharing the scene with you. Sometimes, your lines may call for intentionally interrupting your co-actor mid-speech. Here is an example:
Character 1: “You know I’d never intentionally break your favorite coffee mug. Can’t you see that—”
Character 2: “How can you say it wasn’t intentional when I saw you throw it on the floor?”
In this case, character 2’s cue is the line, “Can’t you see that—” This line prompts you to speak your own line.
Sometimes, a cue can be a change in the physical scenery, such as a change in lighting, a sound effect or the exit/entry of another character.
Regardless of the type of cue expressed in the script, when working on how to memorize a script fast, it’s crucial not to overlook your cues.
